The last 15 minutes were hard to watch.  That much of melodramatic goodbyes is painful.  Donna's grandpa at the end made it bearable.

Introspective dribble as far as "Oh my goodness, look what you've done to the Daleks."  They're a race of evil mutants heck bent on destroying the whole universe, and the weenie Dr. Who writers have their characters gnashing their teeth over wiping out the Daleks to defend the universe.

Good grief.
